Why dont trade winds blow straight toward the equator

Trade winds. trade winds, movement of air toward the equator, from the NE in the Northern Hemisphere and from the SE in the Southern Hemisphere ... The high air pressure in these belts forces air to move toward a belt of low air pressure along the equator called the doldrums.

The surface air that flows from these subtropical high-pressure belts toward the Equator is deflected toward the west in both hemispheres by the Coriolis effect. These winds blow predominantly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere.
